To 'all whom t may concern.'

Be it known that I, WALTER H. REDMAN, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Hair Clippers, of which the following is a specification.

The invention-pertains to the class of hair clippers used by barbers and'others for cutting the hair of persons, horses, dogs and other animals, and one object of the invention is to produce a novel construction of clipper in which the cutter-plate is afforded an ease of movement which tends to relieve it of frictional wear, while at all times being irmly seated over the comb-plate, and which facilitates the general use and operation of the instrument and lessens the strain on the hand of the barber or other person employing the same. A. further purpose of the invention is to providev a construction which is durable andwhose parts may be readil constructed and assembled and disassem led, and a further purpose of the invention is to retain in my novel construction many of the desirable features of known hair-clippers.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which:

Fig. 1 is a top view of a hair-clipper embodying my invention;

' away, of the upper Fig. 2 is a vertical section, scale and partly broken away, through the same on the dotted line 2-2 of Fig. 1;

Fig. 3 is a bottom view, partly broken structure of the clipper on a larger` above the comb and cutter plates;

Fig. 4 is a detached bottom view of a novel frame which I interpose between the cutter plate and the front lower surface of the cover-plate.

Fig. 5 is a transverse section of the same taken on the dotted line 5-5 of Fig. 4, and Fig. 6 is a vertical section through a portion of the clipper taken transversely through one end portion thereof and is pre-v sente to more fully illustrate the connection of the dependmg pins with the cover plate.

In the drawings, 10 designates the combplate, 11 the cutter-plate, 12 a cover-plate or coveringframe, 13 one handle which is late receives 0F NEWARK, NEW JERSEY, ASSIGNOR, BY MESNE ASSIGN-` INC. (0F N. J1), OF NEW WORK, N. Y., A. COOMT'JION CLIPPER.

rigid with said cover-plate and 14 the pivoted handle or lever by which the cutterplate may be operated, as usual.

The cover-plate is domed upwardly and connected with the comb-plate by means of the usual threaded post 15 and studs 16. 'Ihe post 15 is keyed at its lower end in the rearwardly extending portion of the comb-plate and at its upper portion passes throu h a hole in the cover-plate and is provided a ove the cover plate with aspring-washer 17 and thumb-nut 18, as usual. The studs 16 extend downwardlyfrom the cover-plate and after passing through certain intermediate arts,

hereinafter referred to, enter closetting the comb-plate, on

recess-20 in which is confined a stu 21 extending downwardly from an inner portion of the operating lever 14, which lever is pivotally mounted, as usual, and is to be moved in one direction by hand and in the reverse direction or back to initial position by a coiled spring 22 in a well known manner. The movements of the lever 14 are communicated to the cutter-plate 11 and thereby said its usual sliding movements over the comb-plate.

In accordance with er front face of the cover-plate 12 is smooth and flat and on this face I seat a special frame, numbered as a whole 23, which becomes interposed between said fiat face and the topl of the cutter-plate 11. The frame 23 comprises a top p below the front of the cover plate or frame 12 and is formed with downwardly extending ends 25 and a downwardly extending front edge portion edge thereextends rearwardly an auxiliary plate. 27 which is upwardly' depressed, as shown in the drawings and is less in width than the top-plate 24. The rear edge of the top-plate 24 has a concave recess 28 formed in it, and this recess is to permit of the are movement of the stud 21 when the operating lever 14 is actuated to move my invention the low- 26, from whose lower late 24 which extends the cutter plate. The plate 2a is formed with apertures 29 adjacent to opposite ends of the recess 28, and these apertures permit the passage through them of the studs 16 which extend downwardly from the cover plate 12. The studs 16 and apertures 29 serve to maintain the frame 23 in predetermined position with respect to the cover plate 12 and at the same time permit said frame 23 to he applied to and removed from position at the lower flat surface of theffront portion of the plate 12. rihe lower or auxiliary plate 27 of the frame 23 is formed in its end portions with slots 30 downwardly through which the'lower portions of balls or ball-bearings 31 may project and be engaged by the upper front dat surface of the cutter-plate 11, as shown in if ig. 2. The auxiliary plate 27 of the frame 23 is above the forward flat surface of the cutter-plate 11, which surface l number 32, and the front depending edge 33 of the frame 23 created b the up r depression ofthe plate 27 laps ownwarrii; to the front of the surface 32 of the cutter-plate 11, as shown in l@ i 2, thereb serving to exclude hair or the like from lo ging upon that portion of the cutter-plate inward beyond the cutting tongues thereof. rThe slots 30 are elongated, and preferably only two ballbearmgs 31 will be located in each slot, and the long edges of the slots 30 are below the horizontal plane of the center of the ball-bearings 31, and this feature of construction is important in that thereby, with the upper depression of the plate 27, the ball-bearing? 31 are prevented from escaping from t e frame 23, and said frame 23 with the ball-bearings in position may be handled as a unit and applied to or removed from the instrument without danger of said ball-bearings escaping from the slots 30 or from between the plates 24, 27.

The vstuds 16 extending downwardly from the cover plate or frame l2 thus extend through the apertures 29 of the frame 23 and through the usual slots in the cutter p late 11 and into the customary close-fittln holes in the comb-plate 10, and the stu s 16 when the parts are assembled and secured together by the post 15 and nut 18 serve to ald in properly connecting the comb-plate frame 23' and cover plate 12, and at the same time serve as guides for the cutter-plate when moved b the lever handle 14 and spring 22. I minimize the frictional engagement of the cutter 11 with the comblate 10 by recessing the facing surfaces o both of said plates, as shown in F 1g. 2, and the frictional engagement between the cutter-plate 11 and cover plate 12 1s reduced to the minimum by the interpo- .sltlon of the frame 23 containing and affordlng raceways for the ball-bearings 31, which are free to roll within the slots 30 and travel naeneee with the cutter-plate 11 during the endwise haci; and forth or reciprocating movements of said plate.

My invention mainly resides in providing a construction embracing and arranged for the interposition of the bor-like frame 23 between the lower front portion of the cover plate or frame 12 and top of the cutter plate 11, and in addition the frame 23 is of special form and construction adapting it to the instrument and to be applied thereto and removed therefrom without inconvenience. 'llhe studs 16 are well known in hair clippers, butin the present instance these studs are made long enough to extend through the apertures 29 of the frame 23 and also through the cutter plate 11 and comb-plate 10.

'ihe frame 23 may be formed-up from a single piece of sheet metal or its members may be in several pieces secured together at adjacent edges, as may be preferred.

T he operation of the hair-clipper will be understood without detailed explanation, since the cutter plate and comb-plate will be operated, as usual, through the handles 13, la, spring 22 and the skill of the operator. lin accordance with my invention however the cutter-plate 11 is relieved from unnecessary wear and friction by means of the ball-bearings 31 so that the cutter plate will have an ease of movement not heretofore present in hair-clippers and the strain on the hands of the operator will be lessened due to the lessening of the resistance of the cutter-plate to sliding movement.
